He is showing signs of impatience. Murray insists he will not announce his decision – if, indeed, he has reached one – during the middle of a grand slam tournament, but he shed interesting light on his thinking on the subject of women coaching men, ahead of his third-round match on Saturday against Philipp Kohlschreiber.

“When you get a lot of men in a room, there’s often a lot of egos involved and communication can sometimes be difficult, because not everyone listens,” he says. “When there’s an argument it can get heated, rather than everyone just staying calm. In those situations, women can listen a bit better and take things on board more easily than guys. From a communication point of view, it would probably be pretty good.

“To be honest, whether it’s a man or a woman, when they look at the game it’s just important that they see the differences in the two games. In women’s tennis, the serve isn’t as important as in the men’s game. It’s obviously harder to break – statistics show that. And obviously more training needs to go into preparing for a best-of-five-set match.

“In the women’s matches, you need to start incredibly quickly; you can’t afford slow starts. In a best-of-five match, you need to pace yourself a bit more. So long as they understand that, they can easily cope with both: a man can work with a woman or a woman can work with a man. If they don’t accept that, then there will be arguments.”

He was uncertain if there was a fundamental difference in attitude between male and female players and coaches.

“It’s very easy to generalise when you talk about men and women. Everyone’s different. There are some men who will completely panic when something bad is happening in a match and there will be some women who will panic during matches.

“The ones who make the good coaches are [those] who are able to stay calm in those moments and can give sound, clear advice in pressure situations. When you’ve been there and done it, it’s obviously easier to pass on that sort of advice.”

With that he signalled he would rather leave the debate and look to the immediate challenge in front of him.

Life in the first week of a slam for the game’s best players is all about dodging bullets. Rafael Nadal, Roger Federer and Novak Djokovic have managed it by the sixth day at Roland Garros – although Stanislas Wawrinka, Grigor Dimitrov and Kei Nishikori have not.

Did he remember the country club patrons whistling him off court? “No, but that happens there when you don’t play well.

“Kohlschreiber is a quality player. He’s had big results, beating Novak [in the third round in 2009], and winning last week [at the Düsseldorf Open], so he’s bound to be confident. It’s going to be a very tough match.”
